Heart Diseases Clinical Trials

Arrhythmogenic ventricular cardiomyopathy (AVC) is a genetic condition which affects the heart and can lead to heart failure and rhythm problems, of which, sudden cardiac arrest or death is the most tragic and dangerous. Diagnosis and screening of blood-relatives is very difficult as the disease process can be subtle, but sufficient enough, so that the first event is sudden death. The Mayo Clinic AVC Registry is a collaboration between Mayo Clinic, Rochester, USA and Papworth Hospital, Cambridge University Hospitals, Cambridge, UK. The investigators aim to enroll patients with a history of AVC or sudden cardiac death which may be due to AVC, from the US and UK. Family members who are blood-relatives will also be invited, including those who do not have the condition. Data collected include symptoms, ECG, echocardiographic, MRI, Holter, loop recorder, biopsies, exercise stress testing, blood, buccal and saliva samples. Objectives of the study: 1. Discover new genes or altered genes (variants) which cause AVC 2. Identify biomarkers which predict (2a) disease onset, (2b) disease progression, (2c) and the likelihood of arrhythmia (ventricular, supra-ventricular and atrial fibrillation) 3. Correlate genotype with phenotype in confirmed cases of AVC followed longitudinally using clinical, electrocardiographic and imaging data. 4. Characterize desmosomal changes in buccal mucosal cells with genotype and validate with gold-standard endomyocardial biopsies Read Less

Despite many advances in our understanding of the natural history and progression of chronic kidney disease (CKD) and cardio vascular disease (CVD) in the parent CRIC study over the past 15 years, important questions about key risk factors for these diseases remain unanswered in the AI population. To address this burden of CKD in AI communities Investigators formed a consortium of investigators with extensive experience in conducting research of chronic diseases including diabetes, cardiovascular and kidney disease in AIs of Southwestern US. The proposed CRIC ancillary cohort study of 500 AIs (AI-CRIC) will rapidly improve our understanding of both potential risk factors for CKD progression, as well as the scope of this disease among AIs. This study leverages the current CRIC study and incorporates the planned activities of the next phase of the study - "CRIC 2018" - by implementing contemporary CRIC protocols for kidney and cardiovascular measurement and outcomes.

South Asian (Indian, Pakistani, Bangladeshi, Nepali, and Sri Lankan) individuals have high rates of cardiovascular disease that is not explained by traditional cardiovascular risk factors. Though South Asians represent over one-quarter of the world's population, there are no longitudinal studies in this high-risk ethnic group. The investigators aim to establish a longitudinal study of South Asians at three United States centers to identify risk factors linked to subclinical atherosclerosis and incident cardiovascular disease. The purpose of this study is to understand the causes of heart disease and stroke in South Asians and compare these causes to those in other United States ethnic groups. Read Less

A prospective, open label, multi-center, single arm, observational study designed to evaluate the acute safety and device performance of the Sapphire 3 0.85, 1.0 and 1.25mm diameter coronary dilatation catheter in predilatation of Chronic Total Occlusion (CTO) lesions during percutaneous coronary intervention. One hundred seventy (170) subjects will be enrolled with a target of one hundred fifty-three (153) evaluable subjects by the angiographic core laboratory at up to 15 clinical sites with the Sapphire 3 0.85, 1.0 and 1.25mm diameter PTCA dilatation catheter to pre-dilate CTO lesions in coronary arteries during their index procedure. All subjects will be screened according to the protocol inclusion and exclusion criteria and will be followed through study completion, which is defined as 24-hours post-procedure or hospital discharge, whichever comes first.

The purpose of this study is to test a culturally tailored, smartphone-delivered intervention designed to increase physical activity and reduce risk for heart disease and type 2 diabetes among African American women. Read Less

The purpose of this study is to collect DNA samples from patients undergoing routine care at the University of Chicago. These samples will be tested for differences in genes that may suggest greater risk of side effects or chance of increased benefit from certain medications. The results will be made available to the patient's treating physician and the researchers will track whether or not this information is used in routine health care. Read Less

Our study aims to compare postoperative outcomes, postoperative pain and postoperative quality of lives in patients who receive the standard sternal precautions to those in patients who received self-managed sternal precautions following sternotomy for cardiac surgeries. The purpose of the study is to see if self-managed sternal precautions following sternotomy for cardiac surgeries lead to better quality of lives while maintaining same postoperative pain and rate of postoperative adverse events than standard sternal precautions. Postoperative pain and postoperative quality of lives will be assessed by phone call surveys. Postoperative outcomes will be measured by following the patients for up to a year using electronic medical record. Read Less

Less than 15% of Chinese Americans complete advance directives. That is less than half of the 37% completion rate in the US general population. This disparity in the use of advance care planning between White Americans and Chinese Americans may extend to disparities in end-of-life care. To address such disparities in end-of-life care, we will develop and assess the acceptability of a culturally tailored resilience-building intervention to help Chinese Americans with cancer or heart disease and their family caregivers engage in advance care planning discussions.

The goal of this study is to evaluate the safety and efficacy of the BrioVAD System by demonstrating non-inferiority to the HeartMate 3 Left Ventricular Assist System when used for the treatment of advanced, refractory, left ventricular heart failure. Read Less

This is a phase 0, non-interventional, longitudinal, electronic data capture (EDC) study to facilitate the HEARTBEAT Study project has set out to explore the potential use of smartwatches in collecting and analyzing biometric data to improve the detection, identification, and understanding of cardiovascular diseases and related conditions by SAMSUNG and Tulane. The study will include up to ten thousand adult subjects tasked with wearing a smartwatch to collect digital biomarker data over a 1 year period. Concurrent to smartwatch data collection, subjects will be instructed to complete questionnaires via the Huma Decentralized Clinical Trials (HUMADCT) platform. There are no investigational drugs or interventions administered as part of this study. Read Less

Investigators will determine whether N-of-1 trials, as a pragmatic, participant-centered approach to medication optimization that can overcome key barriers of deprescribing, can lead to increased participant confidence regarding their preference to continue or discontinue beta-blockers in older adults with Heart Failure with Preserved Ejection Fraction (HFpEF).

This study will look at the effects of providing medically tailored meals (MTMs) to people with heart disease for twelve weeks. The primary outcome of the study is the quality of the diet being consumed in week 12 of the study, as determined by the "Healthy Eating Index." Read Less
